I am working on the printing of scale models of cranes in scale 1:50 where some parts are less than 1 mm thick which resin is best suited for this without it breaking quickly the resin must be strong is the grey pro or rigid stronger then the grey v3 version

I’d missed that it’s not available until May - oops. I know that Devcon metal-filled epoxy can be used to press objects, it’d certainly be interesting to see if the same thing can be accomplished with the rigid resin.

Hello, I’m new to SLA printing and was wondering if you could elaborate on your statement of
(but that’s already possible with Grey Std as long as you have a bit of experience with it)?
Is there a specific way Grey std should be handled pre/post printing or modeling?
Thank you for any insight you can give.

Is there a specific way Grey std should be handled pre/post printing or modeling?

That’s a pretty broad question, I wouldn’t know where to begin. You should narrow-down what you want to know, take a look on formlabs support pages where they have a slew of articles explaining the basic of resin handling, and then ask in the General Discussion or Support/Troubleshooting sections of the forum for any unclear points.

We recently received our long-awaited grey pro resin and LT tanks, and have had a couple problems out of the gate. The first print appeared to have several support pillars that stopped building or failed to adhere just above the level of the raft, and the part above it was distorted due to the lack of support. We observed that there was a part of the tank that the resin was not wetting to, so figured this might have been part of the reason.

We lightly scraped and tried again with some other parts, and this time experienced multiple part failures where entire sections of the part (except the raft) did not form. We went in with the scraper again and found several areas where cured resin was stuck to the window. We removed these as gently as possible and are trying another build at this moment, but I notice that the resin is still not wetting well, so there are apparent voids after the wiper comes across, so I’m not optimistic.

Any idea what the problem could be? Was there anything we were supposed to do to prep the LT tank? Anyone else have this problem? Would this be a warranty/replacement-worthy issue?

I have been printing with grey pro and LT tank without issue. I did not do any special prep to the tank. It would at least be a “submit a ticket” worthy issue. These tanks have been incredibly reliable for me so far (over 100 prints, with 5+ resins).
